Is there an equivalent of Accelerate Framework in Corona?

Hi,

I am trying to develop a performance based system for iPhone. It requires implementation of fast fourier transforms and few other signal processing functionalities. In iOS 4 Accelerate framework has optimized functions for all these.
Is there a direct implementation of such functions in Corona SDK? if not can somebody suggest an alternate to make this work in Corona SDK?
Any help will be much appreciated.
